Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional prompt generation tools are used, then text-to-speech output can be generated, but the ease of use deteriorates due to complex waveform representation and poor prosody prediction
Solution Approach 1:
The patent introduces an interactive tool as an intermediary between the user and the complex TTS system. This tool provides a user-friendly interface that translates user intentions into appropriate TTS parameters without requiring users to understand complex waveform representations directly.
Solution Approach 2:
The patent creates simplified representations of speech parameters (pitch, duration, energy) that copy the essential characteristics of waveforms in an easily understandable format, allowing users to manipulate speech synthesis without dealing with raw waveform complexity.
2Productivity
If conventional prompt generation tools are used, then text-to-speech output can be generated, but productivity deteriorates due to inefficiency in achieving satisfying results
Solution Approach 1:
The patent implements real-time feedback mechanisms that allow users to immediately hear the effects of parameter adjustments on speech synthesis, enabling rapid iteration and faster achievement of satisfactory results without time-consuming trial and error.
Solution Approach 2:
The patent applies prosody prediction algorithms that perform preliminary analysis and suggest optimal parameter settings before the user makes adjustments, reducing the time required to achieve high-quality speech synthesis results.
3Manufacturing precision
If advanced TTS technologies are employed, then speech quality improves, but ease of operation worsens due to lack of user-friendly interface
Solution Approach 1:
The interactive tool serves as a mediator that handles the complexity of advanced TTS technologies behind the scenes while presenting a simple, intuitive interface to users, allowing them to access high-quality speech synthesis without needing to understand the underlying complex algorithms.
Solution Approach 2:
The system performs automatic prosody prediction and parameter optimization in the background, allowing the advanced TTS technology to improve speech quality automatically without requiring users to manually adjust complex parameters or understand technical details.
